Sections are created from established groups within the association, after the Executive Board of the association has approved a written petition signed by five percent of the individual association  members. LLA currently has seven sections:

• Academic
• Government Documents Round Table (GODORT)
• Louisiana Association of School Librarians (LASL)
• Louisiana Support Staff Association of Libraries (LaSSAL)
  
• Public
• Subject Specialists
• Trustees

Interest groups are established in response to a petitioned request from twelve or more members of LLA. Interest groups develop around a topic of substantive concern to provide a forum of exchange and generation of ideas, and intellectual development for its members. Interest groups by their nature may be transient, and thus are not permanent structural parts of the association.
